1141 AM PDT Sat Jul 20 2024

.An upper level low will move up from the south along the
California coast late this afternoon, and will tap into
increasing mid-level moisture. Meanwhile, elevated instability
will increase and this combined with a moderate to strong trigger
could result in isolated to scattered thunderstorms this evening
into Sunday morning, and again Sunday afternoon and evening. Given
how dry fuels are, along with continued hot temperatures,
lightning efficiency will be high to very high for fire starts.

PM to 11 PM PDT Sunday.

* IMPACTS...Given the prolonged stretch of very hot and very dry

  Sunday afternoon and evening. Lightning strikes outside of
  precipitation cores are possible and cause for concern.

  it.

* DETAILED URL...View the hazard area in detail at
  https://www.wrh.noaa.gov/map/?wfo=mfr


PRECAUTIONARY/PREPAREDNESS ACTIONS...

Avoid tossing burning cigarettes on the ground, parking hot
vehicles on dry vegetation, and using equipment that can cause
sparks. Follow all fire restrictions. Find links to restrictions
at weather.gov/medford/wildfire. One less spark, one less

If you have not packed your evacuation kit yet, now is the time
to do so. This includes items like important documents and
essentials you cannot live without. Fill your vehicle`s fuel
tank. Visit ready.gov/kit for more information.

Plan now to avoid using equipment that could cause sparks during
the period when critical weather conditions are possible. Visit
weather.gov/medford/wildfire for links to fire restrictions in

go? How will you get there? Who will you call to let others know
your are safe? Visit ready.gov/wildfires for more information.

A Red Flag Warning means that critical fire weather conditions
are either occurring now or will shortly. These conditions

Adel, Lakeview, New Pine Creek, Valley Falls, and Fort Rock
434 AM PDT Sat Jul 20 2024

...AIR QUALITY ALERT IN EFFECT UNTIL 5 PM PDT MONDAY...

The Oregon Department of Environmental Quality issued an air quality
advisory for Klamath and northern Lake counties due to numerous
wildfires burning in the region. DEQ also expects other areas of the
state may see intermittent smoke from ongoing large wildfires,
including eastern Douglas and northeast Jackson counties.

The wildfire smoke combined with forecast conditions will cause air
quality levels to fluctuate and could be at unhealthy levels.

Smoke levels can change rapidly depending on the weather. Smoke can
irritate the eyes and lungs and worsen some medical conditions.
People most at risk include infants and young children, people with
heart or lung disease, older adults and pregnant people.

People can take the following precautions to protect their health:

- Follow local burn restrictions to prevent deteriorating air
 quality.
- Avoid strenuous outdoor activity during periods of poor air quality.
- People with heart or lung problems and young children are
  especially vulnerable. These people should stay indoors while smoke
  levels are high.
- Use certified High Efficiency Particulate Air (HEPA) filters in
  indoor heating, ventilation, cooling and air purification systems.
- Avoid using wood-burning stoves and other sources of indoor smoke
  if possible.

DEQs color-coded Air Quality Index provides current air quality
conditions and ranks air quality as follows: Green is good. Yellow is
moderate. Orange is unhealthy for sensitive groups such as children,
the elderly, pregnant women and those with respiratory conditions.
Red is unhealthy for everyone. Purple is very unhealthy for all
groups. Maroon is hazardous.
